  3. Notes: Explain some difficult sentences to Ss • 1. The seven principal cereals grown in the world are wheat, rice, maize, barley, sorghum, oats and rye. Each fully grown plant consists of heads, leavers and stalks. The head, more commonly called the ear, contains the grains that are used for food.

  4. Notes: Explain some difficult sentences to Ss • 2. The method of growing cereals has changed little, although today it is extensively mechanized and has become much more precise. For many years peasants used an ox and a single plough share, and scattered seed onto cultivated soil. When harvesting there were many people using scythes to reap and thresh the crop.

  5. Notes: Explain some difficult sentences to Ss • 3. Maize originated from South America, but is now grown everywhere that is hot and sunny enough. It is one of the three main world cereal crops ( the others being wheat and rice ). Britain is too cold to grow maize to produce grain, but some is grown as a fodder crop, where the whole plant is harvested while still green and made into silage.

  6. Notes: Explain some difficult sentences to Ss • 4. Wheat is the main crop grown in the UK, usually bringing in more than 13 million tones a year. Half the wheat produced is used as animal feed, particularly for pigs and poultry.

  7. Notes: Explain some difficult sentences to Ss • 5. Oats were once commonly grown as feed for ruminants and horses. Harvesting oats is difficult as the grain and ear fall off easily if they become overripe. Oats are still grown as animal feed and are still particularly popular in the north of England and Scotland as porridge and oat cakes as well as other cereal foods.

  8. Notes: Explain some difficult sentences to Ss • 6.If the grain temperature reaches or excesses the dew point temperature, there will be dew fall on the interface of two batches of grains, the grain with drew fall is apt to mildew.
